Parker Pur 18X20X1 Air Filter 18x20x1

Product Description

The PARKER PUR 18X20X1 is a replacement air filter sized at 18 inches by 20 inches by 1 inch, designed for use in forced-air HVAC systems. Air filters of this type capture airborne particulates including dust, pollen, and debris before they reach the blower and heat exchanger. This filter fits into standard 1-inch filter tracks found in residential and light commercial air handlers and furnaces. Installation and changeout are performed by HVAC technicians or qualified service professionals as part of routine preventive maintenance.

This filter is suited for residential and light commercial forced-air systems where a 18-inch by 20-inch by 1-inch filter slot is specified. It serves as a direct drop-in replacement during scheduled filter changes, typically performed every 30 to 90 days depending on system load, occupancy, and local air quality conditions. No tools are required for standard filter replacement.
